Altered States of ConsciousnessAP PSYCH, MYERS – CH. 7
“His was a great sin who first invented consciousness.
Let us lose it for a few hours.”F. Scott Fitzgerald
Consciousness Our awareness of ourselves and our environment (constantly processing information)
Conscious Processing
•Slow, sequenced•Limited capacity•Good at problem solving
Unconscious Processing
•Fast•Parallel tracks simultaneously
Altered States of Consciousness
Consciousness is a continuum ranging from alertness to unconsciousness.
Manic alertness
High alertness
Waking Consciousness
Drowsiness and daydreaming
REM (dreaming) sleep
Non-REM sleep
Coma and vegetative state
Freud’s States of Consciousness
Conscious◦ Perception, thoughts
Preconscious◦ Memories, stored knowledge
Unconscious◦ Unavailable/hidden◦ Repressed memories,
dangerous/sexual desires◦ Protection from anger, guilt, shame
Sleep“I LOVE SLEEP. MY LIFE HAS THE TENDENCY TO FALL APART WHEN I’M AWAKE, YOU KNOW?”- ERNEST HEMINGWAY
Biological Rhythms Periodic physiological fluctuations
◦ controlled by your “biological clock”
Circadian rhythm - regular bodily rhythms that occur in a 24-hour period
Circadian Rhythm – Fun Facts
Light processed by retina triggers brain to increase/decrease production of melatonin
Can be disrupted/reset by adjusting sleep schedule◦ Jetlag, sleeping in late, etc
Artificial light delays sleep 25-hour circadian rhythm◦ Our ancestors attuned naturally to the 24 hour cycle with the day, but
artificial light and industrialization has interfered with our natural rhythm while the world still operates on a 24 hour schedule. (maybe why we always feel tired)
Sleep Stages Sleep - periodical, natural, reversible loss of consciousness
5 Stages (90 min cycles)◦ 1◦ 2◦ 3◦ 4◦ REM
Awake/relaxed◦ Just before you fall asleep◦ Alpha waves
Stage 1 Slowed breathing, irregular brain waves (typical of unremembered moments)
Sleep talking can occur
Hallucinations – sensory experiences that occur without sensory stimuli
◦ feeling of free falling to be awoken by a jerk
Stage 2 20 minutes into sleep cycle
Periodic appearance of sleep spindles (bursts of rapid, rhythmic brain wave activity)
Stage 3 Lasts only several minutes
Begin to produce large delta waves – the large, slow brain waves associated with deep sleep
Hard to awaken
Stage 4 Combined with stage 3 to last about 30 minutes
Delta waves – deep sleep
Hard to awaken
At the end, sleepwalking or bedwetting or night terrors may occur.
REM Sleep REM sleep – rapid eye movement sleep, a recurring sleep stage during which dreams commonly occur
Occurs about an hour into sleep cycles
Ascend through stages 4, 3, 2.
Sharp, short brain waves – look like waves of stage 1
REM Sleep Heart rate and breathing rise
Eyes dart around behind the lids
Motor cortex is active, but blocks movement messages – essentially paralyzed – paradoxical sleep
Gets longer throughout the night◦ Easier to immediately slip into if awoken towards the morning
Hallucinatory dreams – vivid, story-like
Why Sleep? Not everyone needs 8 hrs (newborns vs teens vs adults)
Unhindered sleep = 9 hrs
Sleep Theories Protection
◦ evolutionary
Recuperation ◦ body and brain
Memory ◦ Shed unimportant info, strengthen important info
Growth◦ Growth hormone – babies sleep more
Am I Sleep Deprived? – True or False1. I need an alarm clock in order to wake up at the appropriate time.
2. It’s a struggle for me to get out of bed in the morning.
3. Weekdays mornings I hit the snooze button several times to get more sleep.
4. I feel tired, irritable, and stressed out during the week.
5. I have trouble concentrating and remembering.
6. I feel slow with critical thinking, problem solving, and being creative.
7. I often fall asleep watching TV.
8. I often fall asleep after heavy meals.
9. I often fall asleep within 5 minutes of getting in bed.
10. I often fall asleep while relaxing after dinner.
11. I often fall asleep in lectures or warm rooms.
12. I often sleep extra hours on weekend mornings.
13. I often need a nap to get through my day.
14. I have dark circles around my eyes.
15. I often feel drowsy while driving.
3+ T’s = YOU NEED MORE
SLEEP!
Sleep Deprivation Depression
Increase likelihood of accidents
Decreased alertness
Decreased concentration
Irritability
Sleep Disorders - Insomnia
Recurring problems in falling/staying asleep
Natural and drug treatments
Sleep Disorders - Narcolepsy
Uncontrollable sleep attacks by falling into REM sleep at inappropriate times
◦ ~5 min◦ 1 in 2,000◦ Brain malfunctions
◦ Underproduction of neurotransmitters that signal alertness
◦ Reticular formation◦ Medication can help
Sleep Disorders – Sleep Apnea
Temporary cessations of breathing during sleep and repeated momentary awakenings
◦ 1 in 20◦ Typically overweight men◦ Irritability due to awakenings
Treatment - weight loss or mask that pumps air to keep airway open
Sleep Disorders – Night Terrors
High arousal and an appearance of being terrified◦ Stage 4, not REM (like nightmares)◦ Intense fear, panic, and movement◦ Mostly in children Sleep Infographic
Dreams“DREAMING IS A PHENOMENON OF PURELY INDIVIDUAL CONSCIOUSNESS, AND CONSEQUENTLY IMPOSSIBLE TO THOROUGHLY DECONSTRUCT BY A COMMUNITY OF RESEARCHERS. BUT DREAMING MATTERS.”-ANDREW WEIL
Dreams Sequence of images, emotions, and thoughts during REM sleep
Lucid dreaming – awareness of dreaming while dreaming
Modern theories:◦ Information processing (to file away memories)◦ To develop/preserve neural pathways.◦ Activation synthesis theory (to make sense of random neural static)
Freud’s Dream theory We dream to satisfy unconscious wishes and desires
◦ Manifest content – the remembered storyline of a dream
◦ Latent content – the underlying meaning of a dream◦ Unconscious drives and wishes that would be threatening if
expressed directly
Freud – dreams are the key to understanding the unconscious
Modern scientists – Unscientific, everyone can interpret dreams differently

Hypnosis
Complete the Attitudes on Hypnosis Questionnaire.Wait for instructions on how to calculate your score.
1. Reverse the value given to statements 6,7,9,10,11,13, and 14.2. Then add all values for the 14 questions.3. Scores can range from 14 to 98. 4. Higher scores reflect more positive attitudes toward hypnosis.
Do you have past knowledge or a personal experience that influenced your answers in the questionnaire?
Hypnosis A social interaction in which one person (hypnotist) suggests to another (subject) that certain perceptions, feelings, thoughts, or behaviors will spontaneously occur
◦ SNL Hypnotist
Power of hypnosis lies in the subject’s openness to suggestion
FAQ - Hypnosis Can anyone experience hypnosis?
◦ Yes – depends on suggestibility and belief◦ Highly suggestible people usually have rich imaginations/fantasies, often
become engrossed in novels, movies, storylines
FAQ - Hypnosis Can hypnosis enhance recall of forgotten events/memories?
◦ No – highly suggestible people can fall victim to leading questions from hypnotist
FAQ - Hypnosis Can hypnosis force people to act against their will?
◦ Sort of – depends on the suggestibility of the subject and the desire to conform to the “orders” of an authoritative figure
FAQ - Hypnosis Can hypnosis be therapeutic?
◦ Yes – has alleviated headaches, skin disorders, asthma◦ No – does not help addictions to alcohol, drugs, or tobacco◦ Post-hypnotic suggestion – suggestion made during a hypnosis session to be
carried out after the subject is no longer hypnotized
FAQ - Hypnosis Can hypnosis alleviate pain?
◦ Yes – hypnotized patients in surgical experiments were found to require less medication, recover sooner, and leave the hospital earlier than nonhypnotized patients
◦ Possibly diverting attention away from pain rather then being in a hypnotic state
FAQ - Hypnosis Is Hypnosis an altered state of consciousness?
◦ Maybe…. 2 theories
YES NO
